I've found the AR of NDS uses some temporary data. According to to Kenobi,these datas are: "- The first one is what I'll call the offset, which is a 32-bits value usually added to the address of the code. - The second one are what I'll call the Dx registers. They are four 32-bits, stored before the code list, which is used by the AR to store/load data. I call them 'Dx repeat value', 'Dx next code to be executed', 'Dx code status' and 'Dx data'. - Finally, there is the 'code execution status', which is a 32bits value that tells the AR if a code can be executed, or can be skipped. This code execution status is changed by the 'if' codes." So how to view them (e.g. the value of offset or the value in dx register) in DS emulator on PC(No$gba/DeSmuME/iDeaS)? Thanks!
